24 MPG combined is an acceptable, if unremarkable, figure for the 2019 Acura TLX FWD with the 3.5L V6. Buyers choosing this configuration are typically prioritizing the smooth power delivery and satisfying responsiveness of the V6 engine over ultimate fuel efficiency. They’re willing to compromise slightly on fuel economy to enjoy a more engaging driving experience in a practical and comfortable sedan.

City and highway performance

The EPA estimates for the 2019 TLX V6 FWD break down to 20 MPG in the city and 31 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine spends more time idling and accelerating. The highway number, however, showcases the benefits of the TLX’s nine-speed automatic transmission (S9), which allows the engine to cruise at lower RPMs for improved efficiency at higher speeds. These numbers are achieved using the car’s standard drive mode, which is optimized for everyday driving. Engaging Sport mode will likely decrease both city and highway MPG, while Econ mode could potentially nudge them higher, though at the expense of throttle response.

Annual fuel cost

The EPA estimates that you’ll spend approximately $2,400 per year on fuel for your 2019 Acura TLX V6 FWD. This figure is based on driving 15,000 miles per year and using the national average fuel price. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and where you live, as fuel prices can fluctuate regionally. If you primarily drive in the city or have a heavier foot, your annual fuel cost could easily exceed this estimate. If you primarily drive on the highway and drive conservatively, you might see that number drop slightly.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy often differs. Drivers report slightly lower city MPG than the official estimate in areas with heavy congestion. Highway MPG can sometimes exceed the EPA figure, especially on long, relatively flat stretches of road. Factors such as tire pressure, vehicle load, and weather conditions can also play a role. A realistic expectation for most drivers is combined MPG figures in the low to mid-20s during everyday driving. Drivers who prioritize fuel conservation and use the vehicle primarily for highway commuting can likely achieve closer to the EPA’s 31 MPG highway estimate.

How it compares

The 2019 TLX V6 FWD’s fuel economy places it in the middle of its competitive set. The Lexus ES 350, another V6-powered sedan, achieves an EPA-estimated 26 MPG combined, offering slightly better efficiency. The V6-equipped Infiniti Q50 comes in around 22 MPG combined, giving the TLX a relative advantage. The BMW 330i, with its turbocharged four-cylinder engine, boasts a more frugal 28 MPG combined, but at the expense of the V6’s signature smoothness and sound.

For buyers considering all Acura fuel economy data, the TLX offers a sweet spot between performance and efficiency within the Acura lineup, especially when compared to the larger RLX, which did not fare quite as well. Shoppers can also review TLX MPG across all years to see how the vehicle MPG changed over time.

Tips to maximize efficiency

The nine-speed automatic transmission is programmed to upshift quickly, keeping the engine in its most efficient range. Avoid aggressive acceleration, which forces the transmission to downshift and burn more fuel. Gentle and progressive throttle inputs will help you stay in the higher gears as much as possible.

Ensure your tires are properly inflated to the recommended pressure specified on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly, especially during temperature changes.

Reduce unnecessary weight in the vehicle. Carrying heavy items in the trunk or passenger compartment can negatively impact fuel efficiency. Remove any items you don’t need on a regular basis to lighten the load and improve MPG.

Use cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration and deceleration. This can help you optimize fuel consumption, particularly on long drives. Be mindful of traffic conditions, however, and disengage cruise control when necessary for safety.

Consider using the TLX’s Econ mode, which adjusts throttle response and transmission shift points to prioritize fuel efficiency. While it may make the car feel less responsive, it can help you save fuel, especially in city driving conditions. Experiment with this mode to find the balance between fuel economy and driving enjoyment that works best for you.
